Plug and Play?
I'm sure this has been covered in this very long thread, but....
Is this Wagner IC basically plug-and-play? Meaning: will the ECU/DDE basically just adjust what it does to accommodate the different air flow and temperature characteristics, hopefully all accruing to improved performance and maybe even better MPG as a side benefit?
And may one assume that you will get a bigger marginal percentage positive effect if you start with a tuned machine than you will if start with a non-tuned machine? I guess that's a tough one to answer without seeing the numbers that we have all been wondering about.
